This may not be aggressive enough, probably PI-control would be preferable and not oscillate as much
..
Right now my reaction is to disable traction control entirely. I think it would indeed be a good idea to disable regen in that case.


I've been testing same with ZombieVerter, best result with ...

When using mostly with zombie I can't see all spot values, just for example I12 and current time values. What makes values to be shown?

Also I think I saw current CAN mappings in the beginning but now shows nothing. Tried to add one mapping which did not show up in UI, so I verified with OIC tool ...

Many thanks, this has been great solution to add wifi range! Will try with external antenna some day to get even better.

are you using Windows? I've some fresh boards coming and will do some step by step instructions for boards out of the box.

The bad size given might be a library version issue https://github.com/espressif/arduino-esp32/issues/6482


I only use Linux, esptool would be nice but I did not get it to ...

In first place I did try wrong branch, after getting correct one it gives me some errors about setValueSdo() function, commented errror lines to get lilygo-tcan compile somehow.

I have not used esptool.py before to flash whole thing, so I compiled using Arduino 2.3.3 and same board settings as ...

I don't know how to put this to not sound quite wild, but... I'm pretty sure the Kempower charger I mostly test my car at doesn't connect PP, either at all or at least not during the actual charging session.


All logs I have taken from many Kempower it does have normal PP value and no problem ...

Ordered some 3B0122291B and sadly those was larger NW16. One from amazon with bleeder seemed to be physically much larger on pictures. So hunt continues

Is anyone familiar with VAG parts, cooling connections are Normaquick NW12 which is not so easy to find. VAG might have part number to connector by itself or hose with connector for sure. Maybe I haven't found good spare part diagram to find part number.

Solved. CAN mapping showed none and always "Command or parameter not supported", no matter if I programmed bootloader and Clara with erase. Finally I did STM32CubeProgrammer full chip erase, which I believe is only erasing eeprom, programmer flash with openocd and voila.

Maybe I got into some ...

My home EVSE is Tesla Wallbox gen 2. Does anyone know is there something tricky with these, does it try to communicate using 5% CP?


This mystery is now solved also. Wallbox plug temperature sensor must haev failed about the same time as I moved to Foccci, I didn't notice Wallbox red LED ...

I might be too tired to find my mistake, cleared clara can map and run previously working oic script which no longer works for some reason. Tried with long time used 0.0.9 and also git version 0.1.0.

oic -n 22 can clear
CAN all mapping removed successfully.

oic -n 22 can add tx 0x109 UdcDivider 0 ...

EDIT: SUCCESS!! Edited hwIf_handleContactorRequest by commenting out contactor 2 delay:
ContactorOnTimer2=0;//-CONTACTOR_CYCLES_SEQUENTIAL;

And Kempower seems to ramp quite fast actually, so I would say these worked before there came contactor delay.

---older thinking---

Did not work before ...

Enable? Just to notice, current code does read button while AC charge, so without mod lock won't release.

Precharge 306v sounds about right for 79% SOC.

Before this log I did long CCS on another station, I highly doubt car contactor fault. I'll check from logs where you found this 324V, so I can see is same jump problem with all Kempower stations, as I just posted one log and tried yesterday two ...

Thank you for investigation! Zombie adds 10 volts over Voltspnt and I did not think that, so it got over the set maximum. Just thinking this request over maximum voltage problem, are there any cases where it would be needed to send higher request, because Clara could just limit request voltage to ...

Lightbulb! Looked into zombie oic logs when charge tests failed, it seems CCS_Ireq rises before actual power delivery and maybe some chargers does not like it. Earlier I did have set flash value of CCS_ILim lower and manually pump it up after charge process started.

So maybe need to watch for CCS ...

Tested few stations today with no success. Found sometimes fail reason being locking motor that explains only few failures. Back at home tried pyPLC EVSE which works with no problem. Am I doing something wrong?

Today was similar as yesterday, except some different stations did not give ...

Now that I set up serial port, here is my next mystery. I have problem with CCS with few station types.

ABC stations uses Kempower, works sometimes, mostly not. Logs from exactly same station that was the first place to test foccci (which was success in first try).
K-lataus/Citymarket not sure ...

Is the problem that foccci/clara enables state C if it sees 5% CP even if the charger isn't talking a known protocol?


Not sure should stateC show in the serial logs, I believe (but not verified) it was not activated yet by VCU chademo FC code. Strange is why wallbox stops totally sending CP ...

My home EVSE is Tesla Wallbox gen 2. Does anyone know is there something tricky with these, does it try to communicate using 5% CP?

This is only AC EVSE I have not got working, now grabbed serial log and it seems to start with 5% and then to 0%. Customized Zom begins AC charge if CableCurrentLimit ...

I got Focci/Clara working with pyPLC in EvseMode. ZombieVerter send zeros as batvtg (0x100) and precharge did not complete (accu 0V), replacing batvtg with correct udc value fixed it. I think its needed for real charging session too:


void FCChademo::Task100Ms()//sends chademo messages every 100ms ...

Oh right, sorry I bothered you with this! I totally forgot to do that on this board, silly me.

Here is the serial log, thank you for helping! PP and CP was already connected to charge port and after that connected Focci. At one point I removed PP resistor for a while and did same for CP bit later. Pretty much nothing happening on pyPlc in evse mode. I did not send any CAN messages during this ...

I ordered seals for spare Payen NJ452. Looks the same, dimensions seems to match, not needed to replace yet.

I got hacked AC interface working with Zombie, few more CAN mapping and some code changes. Clara mods was acOBC main like comment says locking and unlocking. Also calling hardwareInterface_stopChargeRequested() while charging to get button work.

I could not yet get pyPLC EVSE to communicate with ...
